Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the high negative pressure piston type automatic water discharging device comprises a water collecting tank 2 with an opening at the upper end; the upper part of the water collecting tank 2 is connected with a water collecting cover 1; the water collecting cover 1 and the water collecting tank 2 can be designed to be detachably connected, and the detachable connection mode can be a clamping thread mode and the like. A floating ball 4 is arranged in the space in the water collecting cover 1 and the water collecting tank 2; an upper connecting rod 3 is fixed at the center of the upper surface of the floating ball 4, and a lower connecting rod 10 is fixed at the center of the lower surface of the floating ball 4; an upper piston 13 is fixed at the upper end of the upper connecting rod 3; the lower end of the lower connecting rod 10 is fixed with a lower piston 8; the upper piston 13 is arranged in a water inlet pipe 14 penetrating through the water collecting cover 1, the upper end of the water inlet pipe 14 is communicated with the bottom of the drainage pipeline, and accumulated water at the bottom can be conveniently drained in time when the upper piston is placed at the bottom; the lower piston 8 is arranged in a water inlet pipe 14 penetrating through the bottom wall of the water collecting tank 2; the diameter of the drain pipe 7 is larger than that of the water inlet pipe 14, the larger diameter of the drain pipe 7 can facilitate the rapid discharge of water in the water collecting tank 2, and further, the diameter of the drain pipe 7 is 2 to 3 times that of the water inlet pipe 14; a hollow water inlet 15 is arranged on the pipe wall of the water inlet pipe 14 positioned in the water collecting tank 2; a hollow water outlet 9 is arranged on the wall of the drain pipe 7 positioned in the water collecting tank 2, and the hollow lower edge of the water outlet 9 is attached to the inner wall of the water collecting tank 2; a tubular air inlet channel 12 is vertically fixed on the water collecting cover 1 in a penetrating way, and the upper end of the air inlet channel 12 is hinged with a pressure cover 12.1 which is provided with a dent 12.2 on the surface and is made of rubber material; a vertical guide rod 11 is arranged in the air inlet channel 12, and the lower end of the guide rod 11 is fixed with the floating ball 4; when the upper edge of the upper piston 13 is flush with the upper edge of the water inlet 15, the lower edge of the lower piston 8 is above the water outlet 9, and the height of the guide rod 11 extending out of the free end of the air inlet channel 12 is equal to the height of the water inlet 15. In order to better discharge the sewage in the water collecting tank 2, a plurality of sewage discharge pipes 5 which are controlled to be switched on and off by manual valves are further arranged at the bottom of the water collecting tank 2. When the valve on the sewage discharge pipe 5 is opened, the pressure cover 12.1 needs to be manually opened, and the sewage in the water collecting tank 2 is discharged by utilizing pressure balance. A base 6 may also be fixed at the bottom of the water collection tank 2 for supporting the water collection tank 2.
The working principle is as follows: as shown in the attached figure 1, when the utility model is used, the upper end of the water inlet pipe 14 needs to be connected to the bottom of the pumping and discharging pipeline in advance, and the specific connection mode is welding.
When the water level in the water collecting tank 2 is low, the buoyancy is low, and the upper piston 13 and the lower piston 8 are respectively positioned below the water inlet 15 and the water outlet 9. When water accumulates in the suction pipeline with negative pressure, the accumulated water enters the water collecting tank 2 from the water inlet 15 along the water inlet pipe 14. At this time, the lower piston 8 is positioned below the water outlet 9, so that accumulated water can be prevented from flowing out of the water drainage pipe 7. Meanwhile, the factors for preventing the accumulated water from flowing out also include that the negative pressure in the pumping pipeline is in a negative pressure state when spreading to the whole water collecting tank 2 through the water inlet 15. In case of negative pressure inside the header tank 2, the accumulated water inside the header tank 2 is hardly discharged.
When the accumulated water flows in, the air in the whole water collecting tank 2 is in a negative pressure state, and the pressure cover 12.1 with the dent 12.2 is tightly attached to the upper end of the air inlet channel 12 in an adsorption mode through the negative pressure. Since the pressure cover 12.1 is made of rubber, the indentation 12.2 is also deformed by pressure to become rubber attached to the water inlet pipe 14 when the negative pressure is large.
Along with the rising of the accumulated water level, the buoyancy of the floating ball is slowly increased. When the buoyancy force slowly overcomes the self gravity and slowly floats upwards, the upper edge of the upper piston 13 is firstly flush with the lower edge of the water inlet 15, and the upper end of the guide rod 11 contacts the bottom wall of the pressure cover 12.1.
At this time, since the water inlet 15 is not yet sealed, the guide rod 11 starts to press the pressure cover 12.1 with the pressure deformation as the water level continues to rise. It should be noted here that, because the pressure cover 12.1 itself is deformed and sealed by the negative pressure, when the pressure of the guide rod 11 is small, it is not enough to push the pressure cover 12.1 away, and when the pressure cover 12.1 is not pushed away, the guide rod 11 will rather restrict the floating ball 4 and the upper piston 13 from rising, so that the water inlet 15 cannot be blocked, and more accumulated water enters the water collecting tank 2. Until the buoyancy is sufficiently high, the pressure cover 12.1 is suddenly opened, and a large amount of air enters the water collection tank 2. And the upper piston 13 blocks the water inlet 15 due to buoyancy. When the upper edge of the upper piston 13 is flush with the upper edge of the water inlet 15, the accumulated water stops flowing into the water collecting tank 2 because of the blockage of the upper piston 13; at this time, the lower edge of the lower piston 8 is above the water outlet 9 and the height of the guide rod 11 extending out of the free end of the air inlet channel 12 is equal to the height of the water inlet 15.
After the pressure cover 12.1 is opened, a large amount of accumulated water is discharged from the drain pipe 7 with a larger diameter instantly, as shown in fig. 2 and 3. Along with the drop of the water level of the accumulated water, the upper connecting rod 3 and the guide rod 11 can instantly drop, and the upper piston 13 can directly drop to be flush with the lower edge of the water inlet 15. The pressure cover 12.1 will also be replaced at the upper end of the inlet channel 12 by a hinged spring (not shown). When the pressure cover 12.1 is closed back, no negative pressure can immediately occur in the water collection tank 2 due to the indentation 12.2. After the floating ball 4 descends, the lower piston 8 also descends, if the lower piston 8 is above the water outlet 9, the water level of accumulated water can continue to descend until the lower piston 8 descends to the lower edge of the water outlet 9 to finish plugging the water discharge pipe 7 due to air leakage caused by the dent 12.2, and a time delay effect is achieved.
When the drain pipe 7 is blocked, the pressure in the water collecting tank 2 can be slowly increased; finally, the pressure cover 12.1 is tightly pressed on the upper end of the water collecting tank 2 through deformation by utilizing negative air pressure in the pumping and discharging pipeline.
